[lazarus] Patches to Shanes files

[Shane Miller]

I am using Strings but in Delphi they are really AnsiStrings.  I guess I am assuming that they are AnsiStrings when declared as Strings.

If StrAlloc remembers extra junk (which would be a bug) then how did you get around it?

I was having the same problem a while ago.  Are you using AnsiStrings?  I
remember that PChar worked well with AnsiStrings, but that the StrAlloc
method would remember extra junk, no matter how I initialized the string
before copying.
